    • An electronic imaging device having a plurality of photosensitive cells arranged in an array to form a frame region, the frame region being composed of a plurality of frame sub-regions each frame sub-region corresponding to a sub-set of photosensitive cells, the device comprising
      an array controller configured to expose each of said frame sub-regions during an exposure duration wherein the exposure of at least some of said frame sub-regions occurs at different times during a total time of exposure of the frame region,
      a flash unit for illuminating a scene to be imaged during a flash time duration
      an activator for activating the flash unit to illuminate the scene to be imaged at a flash time delay determined in dependence upon said exposure duration of a frame sub region and the flash time duration;
      an image data acquisition unit for acquiring a set of frames of the scene wherein the time of occurrence of a flash event within a frame shifts temporally from frame to frame; and
      an image reconstruction unit for constructing a sequence of images from the frame sub-regions of the acquired frames.
    • 1。一种电子成像装置,其具有以阵列排列的多个光敏单元以形成帧区域,所述帧区域由多个帧子区域组成,每个帧子区域对应于光敏单元的子组,所述装置 包括:阵列控制器,被配置为在曝光持续时间期间暴露每个所述帧子区域,其中,在所述帧区域的曝光总时间期间,所述帧子区域中的至少一些的曝光发生在不同时间;闪光单元, 在闪光持续时间期间照亮要成像的场景的激活器,用于激活闪光灯单元,以根据帧子区域的曝光持续时间和闪光持续时间确定的闪光时间延迟照亮待成像的场景; 图像数据获取单元,用于获取场景的一组帧,其中帧内的发生闪光事件的时间在帧间随时间移位; 以及图像重建单元,用于从所获取的帧的帧子区域构建图像序列。
